First of all,
i'm jewish, so don't take offense by this title,
I just seemed to notice,
I seem to have a total obsession with well,
so do some stores,
"Snap Boutique" here in Cincinnati,
and even Kitson.
I don't mean jewish stars,
I mean the Chamsa, or Hamsa, meant to ward of evil.
My Necklace from a gift shop.
A few examples [all from www.shopkitson.com there are even more on the site, just search "hamsa" ]
